Abstract
Described herein is a portable, low power consuming optical particle counter calibration verification system and reliable and sensitive methods for verifying the calibration status of a gas or liquid particle counter. The calibration verification systems described herein are useful for quickly determining the calibration status of an optical particle counter at its point of use, as well as for allowing the end user to determine if an optical particle counter is in need of a recalibration before the recommended calibration schedule suggests.
